BGP ignores incoming packets that already contain their own AS number.
This is part of loop prevention.
You can use the "allowas-in (#)" command to override this, but for the
R&S exam scenarios I can't imagine any reason this would be necessary.
If you are preparing for the C&S lab, then know the command.

Subject: About local AS in AS-PATH?
If local AS is in the AS-PATH, that means traffic in local AS transit
other AS and come back, will it be automatically removed ? If not, I
have to configure As-path filter to do that?
